DIRECTION INDICATOR.

Application filed February 11, 1827, Serial No. 167,480, and in Germany October 12, 1925.

This invention relates to a direction indicator to be operated mechanically from the drivers seat and having the shape of an arrow with a coloured glass pane adapted to get in front of the head lamp. The point of the arrow is arranged so that it can be lighted separately. The arrow is oscillatably mounted on a pin fixed on a carriage which can be shifted between the two head lamps horizontally to the left and right. When the arrow is brought out of its central position or position of rest, in which part of the point projects over the radiator as a control for the driver, it travels first in. lateral direction towards the right or left head lamp to be then oscillated. so that its coloured signal pane gets in front of the head lamp. The arrow transforms this head lamp into a signal, its illuminated point projccting in lateral direction over the outlines of the vehicle so that it indicates also to the rear the change of the direction of travel.

Known arrangements of this kind comprising a direction indicator in the shape of an arrow standing in front of the radiator, having a coloured glass pane and adapted to be oscillated around its axle to be brought in front of the one or other head lamp, present the inconvenience that, when the head lamps stand wider apart, the arrow must be very long; such a long arrow would project too much over the radiator and consequently impede the view.

An embodiment of the invention is shown, by way of example, in the accompanying drawing in which:

Fig. 1 shows in front elevation a motor car with the improved direction indicator.

Fig. 2 shows in front elevation the carriage, the arrow being indicated in dash lines.

Fig. 3 shows the guide bar with the car ri age in vertical section.

In the interval between the two head lamps of a motor car a guide bar a is fixed which at the middle has two notches 7). On this bar a coloured carriage c is slidably mounted which has two upper and two lower springcontrolled pins d and e. On a pin 9 fixed in the carriage 0 an indicator hand f in the shape of an arrow is oscillatably mounted which has a glass pane h and a point 2'.

adapted to be lighted separately. On the rear side of the lower half of the arrow a nose is is arranged. At the right and left in the bar, in the one or other direction towards the corresponding head lamp the nose 7c of the vertical arrow 7 strikes against the corresponding abutment pin Z so that the arrow f oscillates and gets into the horizontal position the coloured glass pane it getting in front of the corresponding head lamp the lighted coloured point i projecting over the outlines of the motor car.

After the car has run over the curvature of the road the arrow is returned, into its central position and oscillated by gravity as soon as it has left the abutment or guide pin Z, the spring controlled pins 03 and e checking this oscillating movement.

We claim A direction indicator for motor cars comprising in combination a horizontal guide bar on the front of the radiator between the two head lamps of the car and having at the middle two notches, an abutment and guide pin at each end of said bar and below the same, a carriage slidably mounted on said horizontal bar, spring-controlled pins on said carriage designed to come into engagement with said notches, a pin on the front side and at the middle of said guide bar, an arrow oscillatably mounted on said pin and of such length that in the vertical position of rest its point projects from the radiator of the motor car, a nose on the rear side of the lower portion of said arrow, a coloured glass pane in said arrow adapted to be placed in front of the corresponding head lamps when said arrow is turned into the horizontal position by said nose striking against the corresponding abutment pin at the shifting of said carriage, and means for lighting the head of said arrow In testimony whereof We afiix our signatures.
